SIGHT FOR GUNS.

SPECIFICATION forming part of Letters Patent No. 664,927, dated January 1, 1901. Application filed April 16, 1900. Serial No. 12,974:- (No model.)

much farther back and attached to the stock. 3 5' .To all whom it may concern:

Be it known that I, ELIHU OUNYNGHAM CHURCH, a citizen of the United States, residing in the city of New York, borough of Manhattan, and county and State of New York, have invented an Improvement in Sights for Guns, of which the following is a specification.

My invention relates to firearms which have front and rear sights.

Figure 1 is, except in the sectional detail of the parts adjoining the rear-sight leaf, a

side elevation of portions of a rifle and of the sights, parts being broken away. Figs. 2, 3, and 4 show elevations of two kinds of rear sights and cross-sections on the lineZ Z of the gun stock and barrel vertical and inclined. Figs. 5 and 6 are perspective views of a portion of a rifle with its front and rear sights, Fig. 6 showing the rifle turned to the left from the vertical plane of Fig. 5.

Various means have heretofore been devised for the purpose of warning the marksman when the rifle-sights are out of plumb, and, if they are, to enable him to properly adjust them in that respect. My invention renders unnecessary any such devices and enables the marksman to take a correct sight even though the barrel of the gun he turned to the right or left, Fig. 6, on the axis of the bore, and there is no need in such case of adj usting the gun to a vertical plane.

' In the drawings the rear sight is shown located forward of the breech and above the fore-arm; but, if desired, it may be placed Any kind of front sight may be used, and, if desired, it may be placed on the side of the barrel, the rear sight being then also attached to the side.

A is the fore-arm.

B is the barrel.

0 is a rear-sight leaf upon which slides the eyepiece H in which is the notch b.

E and G are difierent kinds of front sights.

In Fig. 4 is shown a disk form of peep-sight.

In none of the existing rear sights does the sight-leaf oscillate.

I construct the sight-leaf C so that it will oscillate upon an axis. This axis is a line to, Figs. 1, 5, and 6, which passes through the tip m or ball g of the front sight E or G and is parallel to the axis h h of the bore of the gun, Figs. 1, 5, and 6. The sight-leaf is Weighted, so that when supported on the axis the line of its center of gravity always passes through the notch 19 or peep-hole f of the sight.

What I claim, and desire to secure by Letters Patent, is

In combination with the front sight of a gun, an oscillating rear-sight leaf suspended upon an axis of oscillation that is parallel to the axis of the gun-bore and passes through the sight-point of the front sight, substantially as shown and described.
